Rapid bus service

Rapid bus service

A rapid bus service (RBS) is a rapid transit corridor for buses, located either in the centre of the street or curbside. A section of Le Corbusier Blvd. in Laval is an example of an RBS.


A new rapid bus service has been commissioned on Pie-IX Blvd. in Montréal and will be serving two stops in Laval: Saint-Martin and De la Concorde.
To know everything about the SRB Pie-IX, check out the official page
Pie-IX rapid bus service will be running from Saint-Martin Blvd. in Laval up to Pierre-de-Coubertin Ave.

STM line 439 will run in Laval on weekdays only, except on statutory holidays.

  • The best transfers for using the RBS in Laval:
    • Saint-Martin station: routes 48 and 50
    • De la Concorde station: routes 42, 48 and 58
    • Saint-Martin park-and-ride lot (managed by the STM)


  • Routes 52 and 252 will be the only STL routes to use the RBS:
    • When they are Montréal-bound, the buses will only serve D’Amos station on the other side of the bridge, near Henri-Bourassa Blvd. These bus routes will allow riders to transfer onto STM route 439.
    • They will keep the same schedule and same route as now and will continue their usual route to Henri-Bourassa metro (orange line).

Pie-IX rapid bus service can transfer to routes 50 and 48 at Saint-Martin station and routes 42, 48 and 58 at De la Concorde station.
